Alright, so, back story is My dad and I are thinking(well I WILL be, but he might split cost) about reloading, and while researching, I found loads for 80 and 90 Grain .223 on Hodgdon's Website, but for the Cartridge Over All Length, it was something like 2.5 something... Sierra's has it listed for the 90 as same, and the 80 at 2.260... We're both looking at starting off with reloading 223 first because we both of ar15's, 1-7 twist rate etc. So the question is, what IS the heaviest load That ya'll are aware of, that's safe, in .223, and which manual's it going to be in. Any and all assistance is appreciated. Furthermore I accept the disclaimers of "it's not my fault if you blow your face off" and other such things. THANKS!!!!
